In August 2018, Oxley detectives launched Strike Force Radius, backed by the local Target Action Group and Crime Management Unit, to investigate the supply of illicit drugs and guns in the Tamworth area.

Police said since the start of the secret Radius investigation, officers have seized more than 450g of ice, eight firearms, including pistols, shortened firearms and rifles, ammunition, and two electronic stun devices.

During the searches on Wednesday, officers seized two replica firearms, ammunition, mobile phones, electronic equipment, jewellery, cash, prescription drugs, prohibited drugs, and a NSW Police Force jacket.

Oxley Acting Superintendent Kylie Endemi said the arrests are a testament to the collaborative and dedicated investigative work by police.

"Strike Force Radius detectives have been investigating the activities of this syndicate for over 10 months, and these results can be directly attributed to their hard work," she said.

"Prohibited drugs are incredibly dangerous - and ice is renowned for tearing communities apart - so we need to do everything we can to remove it and those supplying it from our local area.

"It is of particular concern to us that an illicit business, known to those that visit as the 'ice castle', has been operating in our community; but we take great satisfaction in dismantling such a destructive network.

"These arrests also serve as a timely reminder that just one firearm in the wrong hands could be fatal and police will continue to target anyone who illegally possesses and supplies guns in the Oxley Police District.

"Our officers work tirelessly to make Tamworth the safest place to live, and we will continue to seize prohibited drugs and illegal firearms targeting criminal activity at all levels."
